History of the Peloponnesian War

From Eordia also were driven the Eordians, most of whom perished, though a few of them still live round Physca, and the Almopians from Almopia.

These Macedonians also conquered places belonging to the other tribes, which are still theirs—Anthemus, Crestonia, Bisaltia, and much of Macedonia proper. The whole is now called Macedonia, and at the time of the invasion of Sitalces, Perdiccas, Alexander's son, was the reigning king.

These Macedonians, unable to take the field against so numerous an invader, shut themselves up in such strong places and fortresses as the country possessed.

Of these there was no great number, most of those now found in the country having been erected subsequently by Archelaus, the son of Perdiccas, on his accession, who also cut straight roads, and otherwise put the kingdom on a better footing as regards horses, heavy infantry, and other war material than had been done by all the eight kings that preceded him.
